The tool you have is a waste of time, you can get a cheap DA from Argos (I think it's around £55) that will be more than enough for what you need it for. The rubbing compound you are using isn't that great, I'd recommend Menzerna FG400 for the compound stage followed by Meguires M205 for polishing. A compound will need to be followed up by a less aggressive polish for optimum results. It's not a quick process but 100% worth it.

As stated above watch some of AmmoNYC videos on YouTube for the basics
